Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1, this utility model is a kind of exhaust pressure relief valve, including valve body 0, valve body 0 has a ladder hole, ladder hole includes an inlet segment 1 and stage casing 2, stage casing 2 diameter is more than inlet segment 1, is slidably provided with one first end socket 3 in stage casing 2, and the first end socket 3 is resisted against stage casing 2 and inlet segment 1 joint under one first spring 4 effect；Inlet segment 1 sidewall and an exhaust passage 5 connect, in the middle part of this exhaust passage 5, internal diameter is less than the internal diameter at two ends, one second end socket 6 it is slidably provided with in the middle part of this exhaust passage 5, second end socket 6 is resisted against exhaust passage 5 and the joint of inlet segment 1 under one second spring 7 effect, stage casing 2 sidewall and a pressure release passage 8 connect, being slidably provided with the 3rd end socket 9 in this pressure release passage 8, the 3rd end socket 9 is resisted against the joint of pressure release passage 8 and stage casing 2 under the effect of one the 3rd spring 10；Pressure release passage 8 connects with a fourth lane 11 jointly with above exhaust passage 5, and fourth lane 11 is positioned at valve body 0.Use this utility model of said structure by arranging ladder hole, exhaust passage 5 and pressure release passage 8 in valve body 0, and by the first end socket the 3, second end socket the 6, the 3rd end socket the 9, first spring the 4, second spring 7 and cooperation of the 3rd spring 10, realize first gas in pipelines being discharged when electromagnetic pump starts, and within pressure exceedes set point, carry out pressure release, purely mechanic structure is run, working stability, reduces and safeguards, with low cost；Degassing function and decompression function are integrated simultaneously; and exhaust passage 5 exports with pressure release passage 8 and all connects with fourth lane 11; reduce assembling pipeline and finished product; can aerofluxus (gas in pump is discharged) again can pressure release (whole system is carried out overvoltage protection); aerofluxus and pressure release effect can be reached simultaneously; electromagnetic pump can be made under given conditions to draw water or quickly draw water, when electromagnetic pump pressure exceedes the force value of setting, play again overvoltage protection effect.Concrete operating principle is as follows, electromagnetic valve starts, inlet segment 1 is blocked by the first end socket 3, along with inlet segment 1 internal gas pressure increases, to move on second end socket 6, now air in electromagnetic pump is rushed exhaust passage 5 to discharge, electromagnetic pump continues to pump water to inlet segment 1, inlet segment 1 pressure quickly increases, it is pushed into the second end socket 6 on being continued by second end socket 6 and closes the upper end of exhaust passage 5, inlet segment 1 pressure continues to increase to promote the first end socket 3, now electromagnetic pump starts normal water supply, when the hydraulic pressure in ladder hole exceedes setup pressure value, 3rd end socket 9 is backed down, water in ladder hole flows out in pressure release passage 8, reduce hydraulic pressure in ladder hole to after normal level, first end socket 3 seals pressure release passage 8 under the effect of the first spring 4 again, electromagnetic pump normal water supply.
As it can be seen, the second end socket 6 two ends are arranged to coniform, lower end, exhaust passage 5 has one first annular protruding 12, exhaust passage 5 is provided above an aerofluxus post 13, being provided with one first through hole 14 in aerofluxus post 13, second spring 7 one end is resisted against on aerofluxus post 13, and the other end and the second end socket 6 connect.Second end socket 6 of this structure can upper end and lower end to exhaust passage 5 seal efficiently and effectively；Wherein, some positioning strips radially it are provided with on the sidewall of the second end socket 6, some detents it are provided with on medial wall in the middle part of exhaust passage 5, detent carries out coordinating guiding with positioning strip, it is stable that the setting of detent and positioning strip can ensure that the second end socket 6 moves up and down, not vibration, it is ensured that its perpendicularity；The cone shape cone angle on the second end socket 6 top is 40 °, and this cone angle can ensure the most still can be to carrying out good sealing above exhaust passage 5.
As it can be seen, the end being relatively distant from inlet segment 1 in ladder hole is provided with one fixes plug 15, being provided with one second through hole 16 in fixing plug 15, first spring 4 one end is resisted against on fixing plug 15, and the other end and the first end socket 3 connect.The pressure adjustable joint of the first spring 4 so that the pressure that starts of the first end socket 3 moves to pressure topmost more than the second end socket 6.
As it can be seen, be provided with a pressure regulating seat 17 in pressure release passage 8, threadeding between pressure regulating seat 17 with pressure release passage 8 medial wall, be provided with a third through-hole 18 in pressure regulating seat 17, the 3rd spring 10 is arranged between pressure regulating seat 17 and the 3rd end socket 9；By the pressure of screw-in depth regulation the 3rd spring 10 of regulation pressure regulating seat 17, and then regulation setup pressure value.Being provided with one second annular protrusion 19 bottom pressure release passage 8, be provided with a block rubber 20 at corresponding second annular protrusion 19 of the 3rd end socket 9, the cooperation of block rubber 20 and the second annular protrusion 19 can reach preferably sealing effectiveness.
Above-described embodiment is preferred version of the present utility model, and this utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement on the premise of this utility model spirit, and modification or the replacement of these equivalents are all contained in the scope set by the application claim.
